Problems solved by technology

According to the current MEMS technology, the diameter of the probe is generally more than 2mm, and it is difficult to achieve a diameter of less than 1mm or even a micron level, which also greatly limits the scope of use of the endoscope.

Abstract

The invention provides an endoscope which comprises a connecting optical fiber, a self-focusing lens, a slant reflection mirror and a motor. The connecting optical fiber is connected with the tail portion of the self-focusing lens, the slant reflection mirror is opposite to the self-focusing lens, the rear end of the slant reflection mirror is fixed with one end of a rotary shaft, the other end of the rotary shaft is fixed with one end of a column magnet, a supporting sleeve is arranged outside of the rotary shaft, the column magnet, the rotary shaft, the slant reflection mirror and the self-focusing lens are coaxial, and a transparent sleeve is arranged outside the column magnet, the rotary shaft, the slant reflection mirror and the self-focusing lens, and the supporting sleeve and the self-focusing lens are both fixed with the transparent sleeve. A pair of plate magnets with opposite S poles and N poles is arranged on the power output end of the motor in the circumferential direction, a power output shaft of the motor is coaxial with the rotary shaft, and the plate magnets are adjacent to the column magnet. The endoscope is high in flexibility, the outer diameter of the transparent sleeve can be less than 1mm and even can reach micron dimension, and a use range is wide. The endoscope is applicable to an OCT system and imaging systems of optical scanning imaging, scanning fluorence imaging, B ultrasonic imaging and the like.

Description

technical field [0001] The invention relates to the field of imaging technology, in particular to an endoscope. Background technique [0002] Today, image-guided intervention technology is widely used in surgery and medical procedures. Endoscopic technology is very useful in guiding diagnosis and surgery when observing columnar organs, such as human blood vessels and digestive tract. Endoscopy techniques can be divided into two categories: non-optical endoscopy and optical endoscopy. There are two non-optical endoscopic technologies worthy of attention: endoscopic MRI and endoscopic ultrasonography, but these two technologies are inconvenient due to low resolution, poor signal-to-noise ratio, expensive equipment, etc. The problem is that the efficiency is very low in practical application. Therefore, in recent years, optical imaging techniques, including traditional endoscopic techniques, fluorescence, confocal, multiphoton microscopy, and coherent optical tomography (OCT ...
